Store invoice number for reference - (Quick solution)

Is your feature request related to a problem? Please describe.

Currently there is no simple way to match a Customer's invoice number to an invoice ID.

If I have the customer email / uid, I can search for all their invoices, and then filter to get one that matches their invoice number, but this is a very long way around.

Describe the solution you'd like

Super simply we just need to add 1 line

stripeInvoiceNumber: finalizedInvoice.number,

to firestore-stripe-invoices/functions/src/index.ts line 200

Before:

    // Write the Stripe Invoice ID back to the document in Cloud Firestore
    // so that we can find it in the webhook.
    await snap.ref.update({
      stripeInvoiceId: finalizedInvoice.id,
      stripeInvoiceUrl: finalizedInvoice.hosted_invoice_url,
      stripeInvoiceRecord: `https://dashboard.stripe.com${
        invoice.livemode ? '' : '/test'
      }/invoices/${finalizedInvoice.id}`,
    });

After:

    // Write the Stripe Invoice ID back to the document in Cloud Firestore
    // so that we can find it in the webhook.
    await snap.ref.update({
      stripeInvoiceId: finalizedInvoice.id,
      stripeInvoiceNumber: finalizedInvoice.number,
      stripeInvoiceUrl: finalizedInvoice.hosted_invoice_url,
      stripeInvoiceRecord: `https://dashboard.stripe.com${
        invoice.livemode ? '' : '/test'
      }/invoices/${finalizedInvoice.id}`,
    });

This is a pretty key field that's just being left out for no reason, it's what the customer sees and needs to be referenced.
